PLUG CONNECTER FOR ELECTRIC LAMPS Filed July 25, 1950 7MWJ Jar?? By @AWMM Alloniey Patented Feb. 16, 1932 THOMAS LAINT, OF DETROIT, MICHIGAN" PL 'UG' CONNECTER FOR ELECTRIC LAMPS Application filed. July 23,

This invention appertains to new and useful improvements for plug connecters for' electric lamps, and more particularly to a plug connecter which is capable of being readily connected to the usual screw base of a lamp to permit quick attachment of the lamp to a wall receptacle. During the course of the following specification and claims, other important objects to and advantages of the invention willreadily become apparent.

In the drawings Figure 1 represents a side elevational view of a lamp equipped with the novel connecter. 15 Fig. 2 represents an inner end elevation of the novel device.

Fig. 8 represents a-sectional view, taken substantially on the line 33 of Fig. 2.

Fig. 4 represents a side elevational view of the conductor shell.

Fig. 5 represents a perspective view of one of the conductor prongs.

Referring to the drawings wherein like numerals designate like parts, it can be seen that r numeral 5 represents a lamp of the usualshape, and provided with the screw'base 6. The novel adapter or connecter includes a pair of sections 7-8, which go together to make up a cylindrical-shaped jacket generally 53 referred to by numeral 9, for encasing the threaded shell 10 within which the screw base of the lamp can be fed.

Each of the sections 7 and 8, is provided with slots 11 extending through the closed end thereof for receiving the prongs 12 and 13. These prongs 12 and 13, are eachprovi'ded with lugs 14 projecting laterally and which engage in recesses in the slots 11, whereby the prongs are entered through the jacket 9. The shell 10 as at 15, while the inner end of the prong 12 extends through an opening in the shell 10 and is disposed laterally at an oblique angle as denoted by numeral '16. Both of the prongs are of spring material, especially the prong 12 against the end portion 16 of which the base of the lamp 5 must contact. A securing member 17 serves to connect the prong 13 isconnected directly to the V 1930. Serial No. 470,170.

sections 7 and 8 together, to retain the same in assembly.

While the foregoing specification sets forth the invention in definite terms, it is to be understood that numerous changes in the shape, size, and materials may be resorted to without departing from the spirit and scope of the ,invention as claimed hereinafter.

Having thus described my invention, what I claim as new is I 1. A .lamp socket of the class described comprising a socket device formed of sections detachably connected together, an outer socket member a threaded shell in the I socket member having an opening in its top part, an L-shaped prong member passing through the closed end of the socket member and having its short arm connected to the top of the shell, a second prong member passing thru the closed end of the socket member with its short arm extending obliquely through the opening in the shell to form the second contact for the lamp bulb.

2. A lamp socket of the. class described comprising a pair of sections detachably con nected together'and formed of non-conductive material, the closed end of the socket. having slots passing therethrough with recesses in the walls of the slots, a pair of resilient prong members passing through the slots and each formed with a pair of projections for engaging the recessesfor holding the prong members in position, a threaded shell in the socket member having'an opening in the top, one of the prong members being connected to the top part of the shell and the other prong member having an obliquely arranged inner end extending through the opening adjacent the walls thereof to form the second contact of the lamp.

In testimony whereof I aflix my signature.

THOMAS LANT.
